Listing all columns from a MySQL database

In this short post, we are going to learn how to list all columns of every table in a MySQL database.
We want to get the name of the column, the name of the table it belongs to and the type of date for that column.

Query

We will be using a simple SQL query, like this one:

select
table_schema,
table_name,
column_name,
data_type
from
information_schema.columns
where
table_schema = 'mysql'
order
by column_name, table_name;

Don’t forget to change the name of the database where you want to list all the columns, that is the “table_schema” value, in the example “mysql“.
